Resistance to antibiotics has been classed by the World Health Organisation as one of the biggest threats to global health. Researchers at the Scripps Research Institute in the United States say they’ve now managed to modify one antibiotic which was becoming ineffective against one strain of bacteria. The new version of the drug vancomycin is now so powerful they’ve labelled it as ‘magic’. It’s 1,000 times stronger and works in three different ways, making it much harder for the bacteria to fight back.
世界衛(wèi)生組織已將人體對(duì)抗生素的耐藥性劃分為危害全球健康最嚴(yán)重的威脅之一。美國(guó)斯克利普斯研究所（Scripps Research Institute）的研究者說，他們已經(jīng)成功改良了一類抗生素使其再次對(duì)抗已產(chǎn)生抗藥性的一組細(xì)菌?，F(xiàn)在，新版萬古霉素藥效極強(qiáng)，科學(xué)家們甚至稱其為“神奇”。新藥的殺菌力是舊版的1000倍，而且它有三種抗菌機(jī)制，從而使細(xì)菌更難反抗藥物的作用。?
Rosa's Fresh Pizza shop in Philadelphia in the United States offers pizza to customers at a dollar a slice. But you can pay for a slice, leave a post-it note, and that slice will be given free to people in need. Owner Mason Wartman hopes other shops will follow. He says that a little kindness could help people turn their lives around.
美國(guó)費(fèi)城的羅薩新鮮比薩店以每塊一美元的價(jià)格向顧客出售比薩。在這里你還可以提前為需要幫助的人支付一塊比薩的錢，在便利貼上寫下寄語，如此一來，這塊比薩就會(huì)被贈(zèng)送給那位需要幫助的人。店主梅森·沃特曼（Mason Wartman）希望其它店鋪也能效仿他的做法。他說，一點(diǎn)愛心就有可能給他人的生活帶來轉(zhuǎn)機(jī)。
